These are K-Ar data obtained on glauconite, a potassium-bearing clay mineral that forms in some marine sediment. Woodmorappe fails to mention, however, that these data were obtained as part of a controlled experiment to test, on samples of known age, the applicability of the K-Ar method to glauconite and to illite, another clay mineral. He also neglects to mention that most of the 89 K-Ar ages reported in their study agree very well with the expected ages. Evernden and others 43 found that these clay minerals are extremely susceptible to argon loss when heated even slightly, such as occurs when sedimentary rocks are deeply buried. As a result, glauconite is used for dating only with extreme caution. The ages from the Coast Range batholith in Alaska Table 2 are referenced by Woodmorappe to a report by Lanphere and others Whereas Lanphere and his colleagues referred to these two K-Ar ages of and million years, the ages are actually from another report and were obtained from samples collected at two localities in Canada, not Alaska. There is nothing wrong with these ages; they are consistent with the known geologic relations and represent the crystallization ages of the Canadian samples.

Musician-free composition As well as developing new physical interface models another channel of exploration was to use electronic musical instruments to free the composer from problems associated with performers and performance; removing the musician from the process of musical production allowing the composer to create pure unadulterated music concepts.

An exploration of the dichotomy between radical culture and radical social change: New, atonal, music was written, new types of theatre evolved and new instruments invented to bring about this utopian age; Arseney Avraamov conducted a huge symphony of sirens involving warships, factory hooters and artillery and proposed the destruction of all pianos to free music of fixed tonation. The Bolshevik government, traditionalists at heart and worried at their lack of control of this anarchic movement, suppressed it replacing it with a manageable propaganda based culture of uplifting, popular socialist realism; many of the former avant-garde were murdered, imprisoned or sidelined for the rest of their lives.

Again, this avant-garde movement was finally suppressed in favour of conservative fascist popular culture during the late s. The project is completely non-commercial and self funded.
